Description
1. Product Description
The TEWS Technologies TPMC815-11 is a single-width, 32-bit PCI Mezzanine Card (PMC) featuring an ARCNET communication interface for embedded computing and industrial automation systems. It uses an ARCNET controller to provide deterministic network communication between compatible embedded systems and industrial devices.
The TPMC815-11 features an isolated hybrid physical interface designed for communication over supported coaxial cable or twisted-pair media. It supports ARCNET data transfer rates up to 2.5 Mbps and network topologies such as star, tree, and bus. The module is suitable for legacy factory automation, industrial control, and embedded applications that require ARCNET connectivity.
The TPMC815-11 is a legacy, non-RoHS version. TEWS documentation identifies the TPMC815-11R as the RoHS-compliant version of the traditional hybrid interface model and records the -11R option as end-of-life in 2020. When sourcing a replacement, confirm the exact suffix, carrier-board compatibility, physical interface, and operating-system driver requirements.
